Was wondering, i have a 11:1 JE high compression piston. n i heard that the 14:1 piston is a big boost. i want a good piston but dont know really whats the best kind for that size. n is that piston gna make my engine be slower from the start due to its size. i had over heard those size pistons r a bit slower from the start but top end their exceptional. i dont want to sacrifice quickness for top speed. whats the best call????

 

Are you....what are u doing with your machine? Do you want to have to purchase race fuel? We need more info to give a good answer to your question. Bill

I run track with it once in a while, but mostly race. but i aint gna be spending no 40 bucks on fuel everytime. f that. octane boost - 5 bucks a pop.

 

pretty sure 14:1 is out of range for octane boost huh? anywho, 14:1 would be a bottom - mid range mod. Not sure what it would do the the top end.

 

The Hi-Comp Ross I run requires 110 at the least. No octane boost will you get you that. You have to run race gas.
